Problem: Formaldehyde, CH2O, is used as an embalming agent. Draw the structure of CH2O including lone pairs. Drawing tips: 1. Click once on the grid, then just start drawing (dick, hold, and drag). 2. Double-click on a letter then type to change the atom label. 3. Click on a bond to cycle through single, double, and triple. 4. Use the lone-pair button to add lone pairs. Note: after using the lone pair button, you will need to click on the bond button if you want to edit the bonds or atoms again.

Given: CH2O

Central atom: C (EN = 2.5) is less electronegative than O (EN = 3.5) so C is the central atom.
